In this paper the author introduces a very practical model to guide school leaders/managers into supporting parental involvement and engagement in their schools. The model is called the Dual Navigation Approach (DNA). This rubric is based on six meta-analyses that he conducted over the last fifteen years. What is presented therefore is a data-based paradigm of parental involvement and engagement, which will help school leaders and managers understand what how these programmes in their schools can become considerably enhanced. The DNA model more fully distinguishes and develops the two primary branches of parental involvement and engagement, i.e. the school-based component and the home-based aspects. According to the author, when these two components of parental involvement and engagement work together student education outcomes can be greatly enhanced. The practical significance of these findings is discussed.
